UNITED DAVID E. BOBGER, OF COAL HILL, PENNSYLVANIA.

SAW FILING AND GAGING DEVICE.

SPECIFICATION forming part of Letters Patent No. 305,660, datedSeptember 23, 1884-.

Application filed March To all whom it may concern;

Be it known that I, D. E. BORGER, a citizen of the United States,residing at Coal Hill, in the county of Venango and State of Pennsyl-Vania, have invented certain new and useful Improvements in Saw-DressingAppliances; and I do hereby declare the following to be a full, clear,and exact description of the invention, such as will enable othersskilled in the art to which it appertains to make and use the same.

The object of this improvement is to produce a saw-dressing applianceadapted to facilitate the filing and gaging of the clearingteeth ofcrosscut-saws to uniform size. These results are attained by themechanism illus trated by the drawings herewith filed as part hereof, inwhich the same letters of reference denote the same part in all theviews.

Figure 1 is a top or plan view. Fig. 2 is a side elevation, partly insection. Fig. 3 is a side elevation with one of thevside plates removed,showing the interior parts and their relative positions. Fig. 4 is anend elevation. Fig. 5 is a view of one of the parts detached and partlyin section.

The body of the dress is made of two plates, A and A, secured by brazingor riveting to intermediate pieces, BB, recessed at b b, and providedwith screw-threaded perforations c, for the attachment and adjustment ofthe brass pieces E by means of the screws 0, affixed thereto in recessesI, forming sockets for thescrew-heads. The upper part of the appliance12, 1884. (N0 model.)

is recessed, and inclines G are made, at the terminations of which is asteel plate, F, dovetailed at f into the side plates, A A, and providedwith slot H, and extending the entire length of the side plates. Thebrasses E are adjustable up and down by the screws 0, for the purpose ofregulating the extent of the entrance of the saw-tooth into the slot Hof the gaging-plate F. The screws D in the side plate A are for lockingthe brasses E in position according to the amount of filing required toput the saw-tooth in order. By placing the cutting-edge of the sawin thespace H the clearing-tooth will enter the slot H in the gaging-plate F,and by filing the tooth down to the plate all of them will be made Luniform with each other, and the saw can be used to much betteradvantage than when gaged in the ordinary manner.

Having explained the construction and operation of my improvement, whatI claim as new, and desire to secure by Letters Patent, 1s-

The plates A A, intermediate pieces, B B, slotted plate F, adjustablepieces E E, provided with screws 0, and the set-screws D, allconstructed and arranged to operate substantially as specified, for thepurpose set forth.

In testimony whereof I affix my signature in presence of two witnesses.

DAVID E. BURGER.
